Patch to allow ftp client to support REST and SIZE commands

[Arun Suresh]

Hi

We use erlang ftp client library (specifically the recv_chunk function of
the ftp module) to fetch large files which are generally several GBs in
size. An fetch/connection error in the middle of a fetch requires us to
start the fetch afresh.

The FTP RFC http://www.faqs.org/rfcs/rfc959.html talks about the REST
command which can be used to restart transmission from a specified point.
Also it talks about the SIZE command which returns the size of a remote
file.

Please find attached my patch proposal that adds the above functionalities
to the existing client.

Regards,
-Arun
